Describe the structural features and mechanism of assembly of Escherichia coli P (Pap) pili. Use a diagram to illustrate you answer. When are these pili used during infection, and how is receptor specificity determined in this system? [ESSAY TYPE QUESTION]
Homework Answers
"pap" stands for Pyelonephritis-associated pili. These pilli are encoded by pap genes. They are assembled via conserved chaperone-usher pathway. Pap D is periplasmic immunoglobulin (Ig)–like chaperone and being a chaperone it assists the assembly and delivery of pili subunits to the outer membrane usher PapC. PapA forms helix fiber on the external cell. PapH anchor the pilli to the membrane. Pap E forms tip of the fibrillum and PapG is the adhesin at the end of a tip fibrillum. PapK and PapF are adaptor subunits. Pap A provides a driving force for the translocation of pili subunits across the outer membrane, facilitating outward pilus growth.
It binds to D-galactose-D-galactose residues on red blood cells. and help in moving up the urethra causing urinary tract infections.

Topic: Bacteria Chemotaxis (E. coli)
1. You are studying the interaction of CheY and the P1-P2
domains of CheA. You have used site specific mutagenesis to replace
F214 of CheA with an alanine residue.
A. What genetic experimental assay could you use to determine
the effect of the F214 to A214 substitution on the interaction
between CheA-P1P2 and CheY. Explain how the assay works.
B. What would be the effect of the F214 to A214 substitution on
the interaction between...

Food Microbiology Purpose To utilize the process of fermentation to make yogurt To describe organisms responsible for food borne illnesses and summarize a recent outbreak Introduction Microorganisms have been used for centuries for food preservation and to improve or change its taste. Evidence exists that yogurt, which is milk fermented by bacteria, has been around for over 4000 years. Today, many of the foods we eat are the result of microorganisms acting on foods for a specific and desired effect....
